Guide to Purchasing Water Filters
Even if you do trust the water treatment carried out
by your local water treatment system, there is still
the bacteria in the pipes delivering the water to your
homes, and any particulates that may enter the system
due to breaches in pipes.
To ensure the best possible water quality, I recommend
you purchase your own water filtration system.
Water Filter Buying Guide
Check the labels on a water filter or any other water
treatment device carefully. They should state:
- What the filter is designed for.
- When it should be changed.
- Whether it has been properly tested or certified.
Water Filter Standards Bodies
The National Sanitation Foundation (NSF), a statutory
body in the United States, tests water filters and certifies
those which meet its performance standards. The label
will list the contaminants which the cartridge will
remove or reduce. The joint Australia/New Zealand standard
(AS/NZS 4348:1995) specifies performance requirements
for household water filters. However, you're more likely
to find NSF standards quoted.
Only a complete assembled filter can be certified
by NSF. This is because the interface between the cartridge
and housing is critical to filter performance. Keep
a record of the cartridge model number when you buy
a filter unit, so that you can replace it with the same
model.
